Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to make widget images change with health?

For a personal project I'm working on, I have this health system in mind where when the player character loses a life, the image in the widget changes. Green is 3/3 health, yellow is 2/3 health, red is 1/3 health. (images are placeholders) What kind of method would I use to achieve this?

Hey there, you can do this 2 ways:

  • Have 3 images and toggle visibility between them

  • Have 1 image and in the code change the brush image

Which do you prefer?

I attempted using 3 images and toggling visibility, but I must have been doing something wrong since I couldn't get them to work.

Having 1 image and then using code to change brush image does sound interesting tough. I would like to try doing that.

Ok so do the following, select the image on the options on the right create a bind function for the brush. In there you have to create 3 make slatebrush nodes for each of the options and then you'll just do 2 branches to determine which one to use.

Rather than making the circle coloured, make it white and use this to colour it:

This way, you do not need to store/create/maintain multiple brushes/images and/or swap them around. Just pick the colour you want. This will also allow you to animate it easily if you wish so - change the colour gradually, for example.

There are as many solutions to this as there are people. Pick your poison.
